    Workflow d’une campagne d'ingénierie sociale "ClickFix", distribuant le malware Emmenhtal ( 🧀 ainsi nommé par Orange Cyberdefense :) https://www.orangecyberdefense.com/global/blog/cert-news/emmenhtal-a-little-known-loader-distributing-commodity-infostealers-worldwide ) → Déploie Lumma Stealer

    1️⃣ WordPress compromis : injection d’un JS obfusqué ( https://urlscan.io/search/#filename%3A%22%2Frecaptcha%2Fabout%2Fimages%2FreCAPTCHA-logo%22 ) pour afficher un faux CAPTCHA uniquement pour les visiteurs Windows.

    2️⃣ Leurrer l’utilisateur : le faux CAPTCHA les incite à copier-coller un code PowerShell.

    3️⃣ Utilisation d’un LOLBIN : ce code utilise l’utilitaire natif mshta.exe pour "jouer" une fausse vidéo ( https://www.virustotal.com/gui/file/74f22344728037b80b1b49340e3bcd3abd5a9abc89a36169ed59d9c674da49f2/content ) via une URL.

    4️⃣ Payload en arrière-plan : en douce, le code exécute le malware deobfusqué via padding. 🎯
